EMERGENCY ANTISKIDDING DEVICE.

To all whom it may concern:

Be it known that l, FREDERICK A. RUFF, a citizen of the United States, and a resident of Newark, county of Essex, and Sta-te of New Jersey, have invented certain new and usefull Improvements in Emergency Antiskidding Devices, of which the following is a full, clear, and exact description.

This invention relates more particularly to a device which is adapted to be quickly placed on or detached from the wheels of automobiles.

The primary object of the invention is to provide asimple and efficient device having one or more treadelements which are adapted to be passed about the casing of pneumatic tires of automobiles in case the wheel or wheels of the automobile should strike a slippery or muddy place tending to cause vthe wheel tires to slip'or skid, which device is so constructed that it may be quickly attached to or detached from the wheel, and which will serve as aneffective means to cause the wheel to quickly grip and hold to the ground, thus avoiding the necessity ofA having a complete armor on the Wheel or Wheels.

Another'object of the invention is to provide a simple and eflicient device which may be cheaply and readilyv made, and which is adapted to be passed about the tire and around the wheel spokes so as to hold the device against unusual movement.

A further object of the invention is to provide a device having simple and emcient attaching elements for the tread members or chains. y y

With these and other objects in View, the invention will be hereinafter more particularly described with reference to the accompanying drawings, Whichform a part of this specification, and will then be pointed out in the claims at the end ofthe description.

In the drawings, Figure 1 is an elevation of one formvof device embodyingmy invention, showing how the same may be applied to the Wheel of an automobile. Fig. 2 is a det-ail plan view 'of the device; and Fig. 3 is a fragmentary View of one end of the flexible'holding member.

The device may have two attaching memberslOand 11 which are adapted to-fit- -on opposite sides` of the wheel, and each. attaching Ymember may 'be madeof heavygsteel wire and may comprlse a body portion. 12

slipped over said end into an opening 16 formed by said hooked portion.

A plurality of flexiblev holding or connecting members 17 formed of heavy cord or otherwise each have a coupling member 18 at each end. This coupling member 18 has a socket portion 19 and a loop portion 20 which is adapted to be passed over the end 15 and by the body 12 so as to be properly andA detachably held in the opening 16 of the hooked portion 14. One of the coupling members 18 of each flexible member. 17 is adapted to be held to the attaching member 11, and the other end may be passed about the spokes, or about the tire or wheel in any other desired Way, andbe fastened to the hooked portions of the attaching member 10 thus holding the said'attaching members on opposite sides of the wheel as shown Fig. 1.

The loo portions 13 extend outward', When the evice'is in use, and to the loop provided With an attaching device 22. This' coupling or attaching device may comprise two members 23 and 24:, both of which may be held to have a relative movement in a rotary direction with relation to each other so as to form a swivelconnection, andsaid attaching devices 22 may be so arranged as to be permanentl held to the attaching members 10 or be etachably held thereto asidesired.`

From-the foregoing it will be seen that a simpleand efficient device is provided wherebythe said device may be quicklyand easily attached about the tire 'of an automobile Wheel or other rotary element to prevent the same skidding or slipping; that more than one device may be used in connection with each wheel if desired; that said device is easily constructed and has many advantages `for emergency and temporary purposes over
